School children frequently fail to adequately understand terms associated with musical pitch although research shows that even infants with normal hearing can perceptually discriminate fine pitch variations. This study investigated children's perceptions of dimensions of sound by focusing on their choice of musical sounds and relevant…

Forty-nine institutionalized mentally retarded Ss (11- to 26-years-old) were tested to determine the interactions of an auditory ability factor and a personality variable (Level of aspiration) in the prediction of performance on nine Spache Diagnostic Reading Scales. (LC)

An item-recognition task was performed with 32 native English-speaking, right-handed adults who listened to eight two-clause complex sentences presented to the left ear, each immediately followed by a probe word…

This report is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The ten papers treat the following topics: speech synthesis as a tool for the study of speech production; the study of articulatory organization; phonetic perception; cardiac…

Twenty-five dysfunctional (either autistic-like or with reading disorders) Ss ranging in age from 2 months to 25 years were studied to determine whether they respond to the same sound more than once. (Author/SB)

A distinction is made between the acquisition of phonetics and of phonology. Their interaction and the ways in which they interfere with each other are discussed. Data on the acquisition of English fricatives for several children are given, and are analyzed separately for the phonological and phonetic aspects of acquisition. (Author/CLK)
